Changes since congestion pricing started in New York

As a long time NYC resident who moved out during Covid but commute to work in the city. I definitely noticed less traffic on the streets and less noise.

I see a lot of talk of other cities that don't have good public transportation. For example, between Flushing in Queens to 8th Ave in Brooklyn, there are privately run buses at affordable rate and get you there at half the time of trains. There are buses from a lot of residential areas in NJ that are closer to NYC that go to port authority (west side, 42nd st) very quickly. In fact, those buses are getting there faster and more comfortable than ever due to congestion pricing.

I'm curious, do other larger cities where commercial is concentrated into one area not have a private mini-bus(es)? I know public transportation would be great, but having a competitive environment for privately own bus services might be the answer to a lot of cities.

In Japan there are almost only private buses. many are run by and around the private train companies as a way to get their trains to be more useful to more people like when a 25 minute walk from the closest station is a 10 minute bus ride and the busses come often enough to be convenient
